What is a pyroxenite in geology ?
Pyroxenite : definition
A pyroxenite is a rare metamorphic rock composed mainly of pyroxenes, resulting from the metamorphism of basic rock or calcareous sediment.
It is also a group name used to designate ultrabasic plutonic magmatic rocks made up of more than 60% of one or more pyroxenes, accompanied by olivine, hornblende, biotite and/or phlogopite, which can lead to certain confusions with the term "pyroxenolite" which are normally dedicated to them.
